非常简单，直译就是空向量，也就是元素个数为0的向量。不过，在MATLAB中，一般称为空矩阵（Empty matrix）。

empty()函数用于检查向量容器是否为空。 用法: vectorname.empty()参数:No parameters are passed.返回:True, if vector isemptyFalse, Otherwise 例子: Input :myvector = 1, 2, 3, 4, 5 myvector.empty(); Output:False Input :myvector = {} ...
bool empty( ) const; 傳回值 true,如果向量是空的,false,如果向量不是空的。 範例 // vector_empty.cpp // compile with: /EHsc #include <vector> #include <iostream> int main( ) { using namespace std; vector <int> v1; v1.push_back( 10 ); if ( v1.empty( ) ) cout << "The ve...
